pyqt-distutils 0.6.2

A set of distutils extension for building Qt ui files

A set of distutils extension to work with PyQt applications and UI files.

The goal of this tiny library is to help you write PyQt application in a pythonic way, using setup.py to build the Qt designer Ui files.

This works with PyQt4, PyQt5 and PySide (tested with python3 only).

Usage

Add the following lines to your setup.py:

# import build_ui
try:
    from pyqt_distutils.build_ui import build_ui
    cmdclass = {'build_ui': build_ui}
except ImportError:
    build_ui = None  # user won't have pyqt_distutils when deploying
    cmdclass = {}

...

setup(...,
      cmdclass=cmdclass)

To build the ui/qrc files, run:

python setup.py build_ui

To forcibly rebuilt every files, use the --force option:

python setup.py build_ui --force

UI Files

The compilation of ui files is driven by a pyuic.json file, which is a plain json file with the following format:

{
    "files": [
        [
            "forms/main_window.ui",
            "package/forms"
        ]
    ],
    "pyrcc": "pyrcc5",
    "pyrcc_options": "",
    "pyuic": "pyuic5",
    "pyuic_options": "--from-imports"
}

Here is a brief description of the fields:

  • files: list of file pairs made up of the source ui file and the destination package
  • pyrcc: the name of the pyrcc tool to use (e.g: ‘pyrcc4’ or ‘pyside-rcc’)
  • pyrcc_options: pyrcc options (optional)
  • pyuic: the name of the pyuic tool to use (e.g: ‘pyrcc4’ or ‘pyside-rcc’)

Starting from version 3.0, you can use a glob expression instead of a file path. E.g., to compile all ui files under the forms directory in package/forms, you could write the following pyuic.json:

{
    "files": [
        [
            "forms/*.ui",
            "package/forms"
        ]
    ],
    "pyrcc": "pyrcc5",
    "pyrcc_options": "",
    "pyuic": "pyuic5",
    "pyuic_options": "--from-imports"
}

Hooks

A pyqt-distutils hook is a python function that is called after the compilation of a ui/rc script to let you customise its content.

E.g. you might want to write a hook to change the translate function used or replace the PyQt imports by your owns if you’re using a shim,…

The hook function is a simple python function which must take a single argument: the path to the generated python script.

Hooks are exposed as setuptools entrypoint using pyqt_distutils_hooks as the entrypoint key. Add the following code to your setup.py to register your onw hooks:

setup(
    ...,
    entry_points={
        'pyqt_distutils_hooks': [
            'hook_name = package_name.module_name:function_name']
    },
    ...)

To actually use the hook, you must add a “hooks” key to your pyuic.json. This property lists the name of the hooks you’d like to run. E.g:

{
    "files": [
        ["forms/*.ui", "foo_gui/forms/"],
        ["resources/*.qrc", "foo_gui/forms/"]
    ],
    "pyrcc": "pyrcc5",
    "pyrcc_options": "",
    "pyuic": "pyuic5",
    "pyuic_options": "--from-imports",
    "hooks": ["gettext", "spam", "eggs"]
}

At the moment, we provide one builtin hook: gettext. This hook let you use a gettext.gettext wrapper instead of QCoreApplication.translate.

Command line tool

Starting from version 0.2, you can use the pyuicfg command line tool to manage your pyuic.json file:

# generate pyuic.json in the current directory, for use with PyQt4
pyuicfg -g

# generate pyuic.json in the current directory, for use with PyQt5
pyuicfg -g --pyqt5

# generate pyuic.json in the current directory, for use with PySide
pyuicfg -g --pyside

# add files
pyuicfg -a forms/main_window.ui foo_package/forms
pyuicfg -a resources/foo.qrc foo_package/forms

# remove file
pyuicfg -r resources/foo.qrc

Requirements

The following packages are required:

  • docopt

Install

You can either install from pypi:

(sudo) pip install pyqt-distutils

Or from source:

pip install .
